Answer:
C. part X
Explanation:
Part X is showing the bases pairing up with each other, which is the process of transcription. You can verify this by making sure A is pairing with U, T is pairing with A, G is pairing with C, and C is pairing with G.
Part Y is incorrect because it is showing TRANSLATION rather than transcription, which are easy to mix up.
Part W is simply showing the DNA, while part Z is showing the polypeptide.
